To all whom it may concern:

Be it known that I, AnoLrH G. CARLsoN, a citizen of the United Statesresiding at Chicago, in the county of Cook and State of Illinois, haveinvented. a certain new and useful Improvement in Rotary Gas-Engines, ofwhich the following is a specification.

This invention relates to rotary gas engines and has for its object toprovide a new and improved engine of this description. a

The invention isillustrated in the accompanying drawings wherein Figure1 is a side elevation of one form of engine embodying the invention;Fig. 2 is an end elevation 'of the device shown in Fig. 1;

12 is a sectional view taken on line 1212 of Fig. 4'; Fig. 13 is asectional view taken on line 13-13 of Fig. 6.

Like numerals refer to'like parts throughout the several figures.

Referring now to Figs. 1 and 2 wherein I have shown one form of engineembodying the invention, said engine is provided with a suitable casingmade up of a section 1 containing a turbine wheel, and a section 2containing the explosionchambers. The engine is provided with a drivingshaft 3 by means of which the power is applied to the driven Thecarbureter 4 is connected to the fuel supply by a pipe 5. The fuelsupply enters the carbureter andis mixed with air and passes to theexplosion chamber by way of pipe 6. Air for the carbureter is suppliedfrom the turbine wheel by means of Referring now to Fig. 3, the turbinewheels 8 are-connected with the shaft 9 so as to drive the same.Connected at the periphery of the turbine wheels 8 are the turbineblades 10. The wheels 8 are also built as fan impellers any desiredarrangement bethereby kept cool at all times. The air enters the casing1 through the openings 12. The air passes up through passage 13 into thehollow part 14: of the first turbine wheel. It then passes through thehollow turbine blade 10 into an air passage way 15 in the casing. Ittravels from this passage way 15 through the stationary blade 11 andthen through the passage way 16. From the passage way 16, it enters thehollow part 1 1 of.

the next turbine wheel and is passed up through this blade and throughthe next air passage 15 and through the next stationary blade 11 andinto the hollow stationary part 16 and thence through the next turbinewheel. The air passes out through openings 17, of which in theparticular construction shown there are three in number. One isconnected with the earbureter 4 as shown in Figs. 1 and 2, and anotheris connected with the port 26 leading to the explosion chamber, and theother leads to nozzles on each side of the nozzle through which theexploded gases pass to the turbine Wheels so that air may be mixedtherewith to prevent the turbine wheels from getting too hot.

Associated with the turbine wheels is the explosion chamber 1'8. In thisexplosion chamber are a series of valves 19 which are connected by meansof a disk 20 with a vents its escape. The valves and explosion chamberare made in halves to facilitate the machine work and are assembled intothe complete structure. The explosion chamber may be Water or air cooledby means of the chambers 24. The gas from the carburetor passes throughpipe 6 into the explosion chamber 18 through the port 25. In order todischarge the burnt gases from the section of the chamber in which theexplosion has occurred and after the valves have moved so as todisconnect this section from the chamber containing the turbine blades,air from one of the. openings 17 is directed through port 26 into suchsection of the explosion chamber and drives the burnt gas out of theport 26*. The ports 25, 26 26 and 27 are controlled by the valves 19.When the explosive mixture enters the port 25, the port 27 will be openso that the air in the section of the explosion chamber into which theexplosive mixture is entering will be driven out through said port 27.The outlet port 26 is connected with a pipe 28 (see Fig. 2) controlledby a. valve 29. As the valves 19 move forward, the port 27 is closed andthe section between the two valves is filled with. explosive mixturethrough the port 25. As the valves move forward this section ofexplosive mixture is carried forward and just as the port 30 is opened,the

gas is exploded by means of the spark plug 31, and passes through theport 30 and the nozzle 32 (see Fig. 3) into the chamber containing theturbine blades. The gas striking the turbine blades causes a rotationthereof,

and then passes out into the exhaust chamber 33. After this mixture isexploded and explosive gas is then received and the operation repeated.

It will be seen that in the construction shown that there are threeexplosive spaces between the three valves, each one being charged withthe gas, the gas then exploded and discharged and then re-charged,making a continuous cycle of operation, the exploded gasunder pressurebeing discharged against the air-cooled blades of the turbine wheel soas to drive the shaft 9. In larger turbines, I may use six, nine,twelve, or any other number of these valves that may be desired. Theshaft 9 is mounted upon suitable hearings in the casing and is connectedwith the driving shaft 3 by reducing gear"- ing. In the particularconstruction shown, the shaft 9 is provided with a pinion 34 whichmeshes with a plurality of gears 35. In the particular constructionshown, there are two of these gears 35, but any other number desired maybe used. The gears 35 engage the internal gear 36 on the frame and aremounted upon a rotating frame 37 which is connected to the shaft 3 so asto rotate it.

Disk 20 which is connected to valve 19 in p sage 42 and passes throughthe nozzles 40 and 41 located on opposite sides of the nozzle 32 throughwhich the hot gases pass to the turbine blades (see Fig. 7). This airbecomes mixed with the hot gas which propel the turbine blades andprevent the turbine blades from becoming too hot. The turbine wheelcasing is also provided with another nozzle 43 (see Fig. 13) throughwhich is dischargedthe air and foul gasdriven out of the explosionchamber through the port 26*. This gas strikes the turbine blades andexerts its force thereon so as to create a certain amount of power. Atthe end of the shaft 9 I prefer to'provide a generator 44 of the magnetotype for ignitionpurposes. This generator may be of any suitable typeand I therefore have not described it in detail. The conductors 45 fromthis generator lead to the spark coil 46 and from this spark coil to thespark plugs .31 and 47 the latter plug being inserted in the passage wayleading from the explosion chamber to theturbine wheel chamber (see Fig.3).

It will be noted that when the engine is in operation, the air set inmotion by the turbine wheel passes through the movable turbine bladesand stationary hollow blades so as to cool them and that it is thisheated air which enters the.explosion chamber to scavenge it and entersthe carburetor to supply air thereto as hereinbefore described.
